UltraWideo 제작자: nonwip

4.4 / 5

Firefox 사용자 14302851 님의 리뷰

Zuerst dachte ich die Erweiterung tut was sie sollte: Youtube Bild auf Vollscreen erweitern. Aber immer wieder bemerkte ich dass mein (extrem schneller) PC völlig lahm wurde. Dann wurden auch noch Mausklicks verspätet eingespielt, was das ganze System durcheinander brachte. Ich bestellte mir deswegen sogar bei Amazon eine neue Maus. Bis ich verstand dass diese Erweiterung meinen gesamten PC durcheinander brachte.

The extension does not do anything with your mouse, nor does it make any actions delayed, because it simply doesn't activate itself until the video on a webpage is in fullscreen mode. Once you go out of fullscreen, it destructs itself.

Kindly try new version and let me know. It could be that in the past v2 keyboard shortcuts feature may have introduced some lag, but in v3 and upwards that's no longer the case and possibility, because it uses browser built-in commands feature.

Please test again and I'd highly suggest you to use incognito (and allow only ultrawideo in incognito) to make sure that it's not some other extension that interfered with UltraWideo, making your actions have input lag.

Kind regards!

Hello,

Last update was: 3 months ago (Jan 4, 2026)

So nothing was changed "recently". It's either something related to Linux or an extension that you have installed that is conflicting with UltraWideo. If you have any extensions that have similar purpose, uninstall them.

Also, have you tried uninstalling entirely and installing again? If you did, and it still does not work, I am happy to check it out over AnyDesk or something that you have on Linux.

I have no clues otherwise why it would stop working for some users. I've been getting straight 1 star reviews with no helpful feedback on GitHub that would help me to debug and resolve the issue.

Aside, working fine for me in Firefox 148 on macOS.

Any help is appreciated!

Best,
Nenad Novakovic.

Перестало работать, на любом из сайтов... (p.s. версия 3.5.4 работает отлично, версия 3.5.5 не работает

This isn't helpful at all. Mind telling me how 3.5.5 isn't working? There's literally only change for the scaling option that makes scaling of X or Y axis - reflect the change of the other that's modified.

Tested in latest firefox and in nightly and it seems to work fine for me still.

Works better for me than the other one, Ultrawidify. Also, the UI is nicer. Only annoyance so far for me is that I can't support it/purchase Premium with just a one-time purchase. I would if that was an option.

Just after a couple days using the video doesn't show correctly. Only half the screen. It cuts off the bottom half

Works well on most pages but recently subtitles stopped working on fullscreen mode on some of them, notably Disney+

It works decently well, but important features are locked behind a paid subscription that somehow requires a github account. I'm usually happy to donate if an extension is useful, but to not even be able to use it outside of fullscreen if I don't? And I didn't see a way to try the paid features and verify they actually work before paying, maybe I missed it.

Hello,

Pro features are indeed locked and there is no trial. The approach is, subscribe to keep extension alive and you will get those finished pro features unlocked as a bonus.

So adding them as "try before you buy - does not make sense in this scenario", sorry.
I do not think that any Pro features are really that much important, all the basic functionality is already there and free to use.

Thanks!

I’ve noticed an issue when using UltraWideo with Apple TV+ in the Firefox browser. When I stretch the video to fill my screen, the Apple TV+ subtitles no longer display correctly. They get cut off or covered up, making them unreadable. This didn't used to happen, I believe. I suspect the extension is applying the stretch only to the

1. Not really. It's freemium, so payment is not mandatory.
2. No, where did you get that misinformation from? It collects zero data.

Works amazing. Please do not add the watermark back as that is a deal breaker for OLED users.

Hotkeys don't always work in firefox. Whyyyyy is there a watermark? I'm uninstalling and searching for an alternative simply because of the dumb watermark.

If they don't work, it's firefox issue. Because extension is using browser's shortcuts API.
Watermark will disappear in 3.5.1, but Mozilla is slow on approval. Should happen this week I guess. Try Chrome?

Thank you for your input. I did not expect this tiny watermark to be huge annoyance, but seeing many negative feedback the watermark is removed in version 3.5.1.

This was originally a 1-star review of a version that had a watermark added in the non-Pro version. After kindly listening to our feedback, the developer changed this, and I can now wholeheartedly recommend the add-on! Much appreciated.

5 stars now, thanks!

OG: Works great for cropping widescreen to 4:3. Although in 3.5.0 a watermark was added for free users, shame it used to be open-source too :/
